405 Heaterectomy
Just put mine back in....
There is a story that Bristol made the 405 by first hanging the heater box from the work's ceiling and then building the rest of the car around it.... Anyway...
One hint for removal re-insertion is to force the forward bulkhead forward about 6 - 10mm with a scissor jack, that's what I had to do to get enough clearance, didn't seem to damage the b'head....
I just took the heater assembly to bits, easy, then cleaned out the dead animal life from the air side, removed the radiator and hosed hot water through it with the radiator at various angles to get at all of it... I think there was more dead water life than air...
I didn't need to cut anything from the air vent pipes, however the rest of my car is in bits so it's fairly easy to get at most of it....
My water valve was stuffed so I got a similar one from the local MG spares guy, it's a common BL type... Don't forget the little O ring that seals it all...
I have pics of the heater controls setup and water valve if needed...
Have fun, Stuart
